摘要： A zoom lens assembly for a camera includes front and rear lens assemblies and a cam assembly mounted in a cylindrical lens barrel. Rotation of the cam assembly results in axial movement of the lens assemblies and change of the focal length. The cam assembly includes discrete front and rear sections respectively defining front lens and rear lens cam surfaces. The sections are attached together with the lens assemblies captured internally. Integral projections on the front lens assembly engage the front lens cam surface and axial grooves in the barrel. Integral projections on the rear lens assembly engage the rear lens cam surface and axial grooves in the front lens assembly. A coil spring urges the lens assemblies apart and against the cam surfaces.

摘要： The camera preferably has a slotted take-up spool which when the film compartment covering door is opened is automatically rotated into an ideal position where a hook in a film-capturing slot thereof has an outward facing orientation ideal for capturing a film leader perforation when the film leader is inserted therein. The slot is preferably configured as a lengthwise passage leading into a hollow axially disposed chamber within the take-up spool, the trailing edge of the slot nearest the imaging station being provided with the hook. This edge is positioned so that it does not come into confronting engagement with the film during initial advance thereof until the film is firmly captively secured over the hook.

摘要： In a camera including a shutter member, a spring urged striker member adapted to be moved from an initial position to a fully cocked position and then released to strike the shutter member to cause the shutter member to move momentarily away from the lens opening of the camera, a drive gear is provided for moving the striker member from an initial to a fully cocked position during only part of the movement of a manually operable film winder member during a film winding operation. The striker member includes a gear segment including a toothed portion provided with teeth meshable with gear teeth of a first portion of the drive gear and a dead motion portion free of gear teeth so that further movement of said drive gear will not move the striker member beyond the fully cocked position, the striker member being held in the fully cocked position by the abutment of the last tooth of the gear segment with the drive gear.

摘要： An infrared ranging system for a battery-powered camera uses a light-emitting diode and associated pulse circuitry for producing a single ranging flash concentrated by a lens into a narrow cone of light generally centrally located in the field of view. The diode is powered by a capacitor bank charged in parallel and discharged in series to provide the necessary current pulse to the diode from a 2.0 volt system. The received pulse is concentrated on a photosensing diode by means of an infrared-passing lens to produce a voltage pulse related to amplitude of the reflected light, and hence to the range to a centrally located object in the field, this pulse being processed to set the state of one or more range-indicating latch circuits. The state of the latch circuits is used to govern the final setting of a driven adjustable focus lens. The system is equally applicable to setting the camera aperture in flash mode wherein the aperture is a range-dependent function.

摘要： A packaged camera assembly comprises a camera enclosed by a clam shell container of elongated rectangular shape so that the container is at least about twice as long as it is wide. A camera is supported between closely confronting transparent main walls of front and rear sections of the clam shell container which have outwardly projecting pockets for receiving the front and rear halves respectively of the camera. The camera is supported in the container so that the long dimension of its front face angles at least about 45 degrees and preferably about 60 degrees from the narrow dimension of the container. The container preferably has a display card sandwiched between said transparent main walls, the card having an aperture through which the camera passes. The container has support means along its long and short margins to support the packaged assembly upright for display with its long dimension upright or horizontal. The display card has camera identifying indicia with letters angled about 45 degrees so that the display card can be read when the packaged camera assembly has either one of the described display orientations.

摘要： A simplified miniature camera features a spring-actuated shutter-striking slider member having a film-engaging finger integral therewith for engaging a film during film advance to move the striker member to an energized position. The slider member energizing spring is disposed to provide not only translational urging to the slider member, but also rotational urging to provide such film engagement. The film engaging member, as well as an arresting pawl configured to arresting engage the takeup spool gearing drive are all integral in a one-piece slider member slidably mounted to a post in the camera body. Exposure is initiated by operator actuation of a rotatable control member rotating the sliding member to disengage the film-engaging finger from its captured state in a film perforation, thereby releasing the slide to strike an impulse shutter. Subsequent rotation of the slider member of the slider energizing spring not only rotates the slider and the film-engaging finger into engagement with a film perforation, but also returns the shutter control system to its dormant state without the necessity for an additional return spring. In one embodiment, a pair of sear portions are formed, one on the camera body, and the other integral with the slider member, and may form either an auxiliary cocking latch for testing the camera with no film in place, or in the alternative, as the normal shutter release latch.
摘要翻译：简化的微型相机具有弹簧致动的快门击打滑块部件，其具有与其成为一体的胶片接合指状件，用于在胶片推进期间与胶片接合以将撞杆部件移动到通电位置。滑动构件通电弹簧被设置成不仅提供对滑动构件的平移作用，而且提供旋转推动以提供这种膜接合。胶片接合构件以及构造成阻止卷绕卷轴传动装置的止动爪都是整体的，可滑动地安装到照相机主体中的柱上的一体式滑动构件。通过操作者启动旋转控制构件来启动曝光，旋转控制构件旋转滑动构件以使胶片接合手指从胶片穿孔中的捕获状态脱离，从而释放滑块以撞击脉冲快门。滑块激励弹簧的滑动构件的随后的旋转不仅使滑块和胶片接合手指旋转与薄膜穿孔接合，而且还使快门控制系统恢复到其休眠状态，而不需要额外的复位弹簧。在一个实施例中，形成一对扣合部分，一个在相机主体上，另一个与滑块部件一体形成，并且可以形成用于在没有胶片就位的情况下测试相机的辅助起重闩锁，或者替代地，作为普通快门释放闩锁。

摘要： A camera shutter cocking system employs a specially configured cam driven synchronously with a film-engaging sprocket to actuate a shutter cocking lever from a released to a shutter cocking condition by means of a cam follower mounted on the cocking lever. The cam preferably has two lobes, each configured to maintain the shutter cocking load on an electric motor drive system generally constant throughout substantially the entire film advancing operation. Excessive terminal overspeed of the motor drive system is thereby suppressed. A one-way clutch between the cam and the sprocket disengages the shutter cocking system from the motor drive during rewind and traps the cocking lever in a released position, thus preventing multiple double exposure of the film if the shutter release button is accidentally held down by the user during this operation.
摘要翻译：相机快门启动系统采用与胶片接合链轮同步地驱动的特殊配置的凸轮，以通过安装在推杆上的凸轮从动件从释放的快门启动状态致动快门推杆。凸轮优选地具有两个凸角，每个凸起被构造成将电动机驱动系统上的快门起动负载保持在基本上整个薄膜前进操作中大体恒定。由此可以抑制电动机驱动系统的过大的超速。凸轮和链轮之间的单向离合器在倒带时将快门推动系统与电动机驱动器分离，并将起动杆捕获在释放位置，从而如果快门释放按钮被意外地按住，则防止胶片的多次双重曝光该操作期间的用户。

摘要： A completely mechanical disc film camera features film advance and shutter actuation by direct mechanical coupling to an external shutter release button. Shutter button actuation is automatically blocked after the fifteenth frame so as to prevent double exposure and film tearing. Selective film-flattening back pressure is applied to the disc film cassette during the terminal phase of the shutter depression stroke immediately prior to shutter tripping so as to hold the film in the proper imaging plane. Back pressure is released during the film advancing phase to as to relieve system loads and avoid film scratching. The film advance is secured by the oscillatory movement of a film notch engaging pawl carried by a claw driven into oscillatory motion by operation of the shutter button. Means are provided for coupling additional mass to the claw during the terminal phase of the film advancing stroke to reduce the speed of film advance, thereby providing protection against film overtravel. To provide for proper initial film advance when a fresh cassette is inserted an automatic film advancing operation is carried out responsive to closure of the door loading system.
摘要翻译：完全机械的光盘胶片相机通过直接机械耦合到外部快门释放按钮来实现胶片前进和快门驱动。快门按钮启动在第十五帧后自动阻塞，以防止双重曝光和胶片撕裂。在快门跳闸之前的快门按压行程的终点阶段期间，对光盘胶片暗盒施加选择性的胶片平整背压，以便将胶片保持在适当的成像平面中。在胶片推进阶段释放背压以减轻系统负荷并避免胶片刮擦。通过快门按钮的操作通过由驱动到振荡运动的爪承载的胶片缺口接合爪的振荡运动来确保胶片前进。提供了用于在膜前进行程的终点期间将额外的质量与爪连接的装置，以降低胶片前进的速度，从而提供防止膜超行程的保护。为了在插入新的盒式磁带时提供适当的初始胶片提前，响应于门装载系统的关闭来执行自动胶片前进操作。
